✦ Synopsis

We present the anomalous magnetotransport observed in a narrow high mobility Hall device; both the peaks and minima in the Shubnikov-de Haas oscillations of the longitudinal resistance appear in the quantized plateau region of the Hail resistance. We interpret this feature as a consequence of an inhomogeneous distribution of two dimensional electron gas and provide a quantitative view with a model based on the edge current picture.
